Asics Metaspeed Edge Paris vs Asics Metaspeed Sky Tokyo:
Which to Choose

Start with the split that Asics designed these around, because it's the whole point. The Edge is built for cadence-type runners — people who go faster mainly by turning their legs over quicker while stride length stays roughly constant. Its geometry is more aggressively tipped forward with a pronounced toe-spring that rewards short, quick, snappy steps. The Sky, by contrast, is for stride-type runners who lengthen their stride as they accelerate; its plate sits flatter and the platform is tuned to give more aerial bounce and float per step, which is why the Sky line skews slightly more toward the full marathon while the Edge is equally happy dropping down toward the half. The foams differ too: the Edge Paris runs on FF Turbo Plus PEBA, firm and quick to spring back, while the Sky Tokyo uses Asics' newer FF Leap (A-TPU) superfoam, which is what lets it hit a remarkably light 163g (men's US 9) versus roughly 185g for the Edge Paris — a real, noticeable weight gap driven largely by the Sky Tokyo being the newer generation. Stack heights are effectively a wash: about 39mm heel / 33mm forefoot on the Sky Tokyo against 39.5mm / 34.5mm on the Edge Paris, so both give you a similarly tall, well-cushioned racing platform. Drop is close as well, 5mm on the Edge Paris and around 6mm on the Sky Tokyo (Asics lists it as 5mm). Both share the same character otherwise: tall, narrow, neutral platforms with no pronation support, a firm race-ready ride that feels stiff and unremarkable at jogging pace but comes alive once you're genuinely at effort, and thin, minimal mesh uppers that trade lockdown and durability for speed. In short, the meaningful differences are gait fit, the Sky Tokyo's newer foam and lighter weight, and the Edge's snappier, more turnover-focused geometry — not cushioning or stability, where they're near-identical.
